In general, consistency in quantity of data points (in each different insight, not the full study sample size), consistency in period, and consistency in types of data (if categories are present) are nice things to reassure you that the data isn’t be stitched together from sources that are actually saying different things with radically different methodology or data structure.
I think its a perfectly reasonable question to ask.

That’s funny, because that’s exactly what they did.
